摘要:
PROBLEM TO BE SOLVED: To provide a repeater apparatus reliably suppressing an interference signal which may cau a range of fluctuation at a point of detection thereof due to a group delay deflection or the like.
SOLUTION: A delay reference signal, which is obtained by causing a plurality of kinds of delay times to a reference signal including the same signal component as that of a receiving signal by a delay device 41, and a digitally-converted receiving signal are input to a correlation integrator 39. A delay reference signal having the highest correlation between the both signals input is determined as a signal corresponding to an interference signal, and a point of appearance of the interference signal is specified. A delay time is specified by a CPU 40, wherein the delay time is parated before and after the point of the appearance as a center by an integral multiple of a unit time width that is an inver number of a frequency of an operation clock in digital processing. A plurality of kinds of suppression signals with a pha inver to a pha of a signal corresponding to respective interference signal at each point specified are generated, and the suppression signals are added to the digitally-converted receiving signal by an adder 34.
